Grade 1 Science: 10 Free Practice Questions

Answer: Light comes in and lets you see the toy
We need light to see objects; opening the door lets light in. Objects like toys do not make their own light. When you open the door, light enters, bounces off the toy, and travels to your eyes so you can see it. Students may think the toy makes its own light, but the toy can only be seen when light shines on it.

Answer: The Sun
The Sun gives Earth light and warmth in the daytime. The Sun is a star we see during the day. It shines light and gives warmth to Earth. So the Sun is the correct answer. Students may pick the Moon, but the Moon is mostly seen at night and does not give warmth like the Sun.

Answer: Light from the Sun bounces off the Moon
The Moon shines because sunlight bounces off it. The Moon does not make its own light. The Sun's light travels to the Moon and bounces off its surface toward Earth. That reflected sunlight is what makes the Moon look bright to us. Students commonly believe the Moon makes its own light, but it only reflects light from the Sun.

Answer: the Sun
The Sun shines in the daytime.

Answer: Sunlight
Plants need sunlight to grow. Plants use sunlight to make their food and grow. Rocks and sand are not needs from the sky, and toys are not living needs. Sunlight comes from the sun in the sky. Students may pick rocks or sand because plants grow in soil, forgetting that sunlight is the need from the sky.

Answer: Air
A plant needs air to live. Plants take in air through their leaves to help make food and stay alive. Along with water and sunlight, air is one of a plant's basic needs. Students may pick objects people use, like a book, but plants need air, not human items.

Answer: Its ears
A rabbit uses its ears to hear sounds. Ears are the body part animals use to hear. A rabbit has large ears that help it hear danger and other sounds around it. Students may pick the tail or feet, but those parts are not used for hearing; ears sense sound.
